IMPROVEMENT IN UPSETTING-MAGHINB.

Beit known that I, J. F. SARGENT, of Tunbridge, in the county of Orange, and State of Vermont, have invented a new and improved Upsetting-Machine; and I do hereby declare that the followingis a full, clear,A

and exact description thereof, which will enable others skilled in the art to make and use the same, reference bein-g had to the accompanying drawings, forming part of this specification.-

VFigure 2 is an end elevation of the same.

Figure 3 is a plan view of the machine.

Similar letters of reference indicate corresponding parts. l

This invention relates to the compressing or upsetting, so called, of iron tires, bands, bars, rods, or other metallic bodies of longitudinal dimensions.

It consists ofv a pair o f levers, operato-d by an oscillating-disk, to which they are connected by links, the said levers having projecting arms, which, when operated, hear down upon the iron bar or rod with the peculiar upsetting motion,vas will, together with the other parts of the machine, be hereinafter more fully set forth.

From the base, A, arises a block, B, which supports the mechanism. On a shaft, a, passing through the block, as shown, is a disk, t, to which are eccentrically attached, by wrist-pins, z', the double links m. m, which latter connect with the levers D, as shown at u. These levers are again pivoted at 1t to a bed-plate, E, set on the top of the block B, and held there by one or more countersunk screw-bolts, not shown.

To hold the bed-plate E more firmly, the block B is sawn not quite across at the top, and a' portion of the wood left, as shown at G, projecting above the sawedend of the block upon which the bed-plate'E rests. The vertical flange of the bed-plate rests against this part, inland is held there by a bar, F, bolted atom to the bedplate, these bolts, by-which the said har is attached, serving as centres, on which the levers D operate. Acentral bolt, n', may be added, if desired. i

The shaft a, on which the disk I; is mounted, passes through the block B, and'on its opposite end is keyed a crank-disk, H, having a. handle, t, as shown. A

The levers D are bent horizontally across the top 'of the bed-plate E, as shown, thus forming arms I', which are the means of producing the clamping action en the iron bar, as will be shown.`

The vertical ange ofthe bed-plate is notched, as shown at e, to permit the proper movement of these arms downward and toward each other, when in the act of clamping the har, rod, or tire, which is shown atS resting .upona metallic die-block, M, which latter rests on the bed-plate, as shown, and is removable. There should be,-

in practice, several of these block s,`of different thicknesses, whereby the permutation of them would provide a number of diifcrentvthicknesses,requisite for upsetting light or heavy work.

In operating this .machine,ithe tire, bar, orl rod. is placed under the arms, and the crank 7a turned. The arms I of thc'levcrs will descend upon the bar and hold it firmly. The metal should be previously bent up at the point to be upset, and,when thus bent, part is clam ed between the two arms of the machine. dlrfeW-blows with the hammer forces the bent part down straight again, and thus accomplishes the upsetting of the bar or rod, to be performed in less time than any other machine, which is an important feature.

The part of the arms I that impinges upon the metal to be compressed is angular, whereby it takes a firm' hold upon all forms of" rods or bars, and is thus suitable for light or heavy work.

I am aware of the existence of various machines for the purpose of upsetting iron, but their operation is slow, and vattended with other objectionable features, which donot obtain in connection with the one above presented, as its compass is small, its action quick and perfect, and at a small outlay of power.

Being simple, durable, and cheap, it supplies a desideratum long felt by ironsmiths.

I claim as new, and desire to secure by Letters Patentl 1. The disk t and links m, or other equivalent devices, constructed and operated substantially as shown and described, in combination with the levers-D and arms I, all as and for the purpose set forth.-

2. The block B and base A, combined :ind forming a, pedestal for supporting the mechanism, substantially as shown and described, in combination with the bed-plate and leversD and arms I, all as and for the purposes set forth. 4

.3. The levers D, formed with arms I, in combination with the links m, disk 11,-and'crnnk z, all constructed,

nrrnnged,a.nd operating in the manner substantially as. herein shown and described.
